Which Two Elements Have The Same Ground State Electron Configuration

Which Two Elements Have The Same Ground State Electron Configuration

Which two elements have the same ground state electronic configuration? ۔

PD and PT

Cu and Ag

Fe and Cu

Cl and wind.

In the ground state, no element has the same electronic configuration.

I am confused. I typed Fe and Cu, but it's wrong.

Help thanks

They are not 2 elements, because in their ground state each element has a different number of electrons, so they all have different sequences.

If you really want to ask who has the same attitude, the answer is A and B.
